To all w from. t may concern.'

Bc 1t known that l, Hanni? l-l. HANCOCK, a citizen o1 the United States, residing at Swampscott, in the county oi" Essen and State ot Massachusetts, have invented certain new and useful improvements in Entension Furniture for Printers, of which the following is a specification. Y

This invent-ion relates to extension turniture for printers, and one object of the invention is to provide extension or adjustable furniture for securinotype within a chase, said 'furniture being composed ol? counterpart members which are preferably inseparable from each other. Another object oit the invention is to provide extension or adjustable 'furniture for printers, in which-although the separate members are preferably inseparable romeach otherthey are made to have uniform thickness in corresponding Jarts from end to end thereb aiilordin a support ior the type that will be set against them on either side thereof, each member preferably being ot pica measurement in length, as well as in breadth. rthe extension-furniture ot the present invention is preferably made for any size ot chase. lltherobjects ot the invention will appear herein. V

rEhe specilied objects being among 4the objects ot the present invention, the same consists ot certain features of construction and combinations of partsto be hereinafter described and then claimed with reference to the accompanying drawings, showing one embodiment of the invention, in which:

Figure 1 is a perspective view ol the ii`nproved printe 1s furniture showing the members collapsed or distended;

Fig. 2 is a* perspective View showing the members partly extended or adjusted;

Fig. 3 is a transverse section; on line 3--3, Fig'. 4;

Fig. @is a plan of one face of the turniture, partly broken away; and

5 is a perspective view of one oit the members of the furniture.

-Referring to the drawings, there are two members l0 and 11, and the construction ot these members is preferably suchthat they are counterparts ot each other, or are twin members. rlhe member 10 is provided with longitudinal tongue 12, which is shown as of the same length as the body portion ot the member 10. rlfhe member 11 has a similar tongue 13. ils shown, the separate mem- Specification of Letters Patent.

bers ot the furniture are oi compound construction, although in practice each member is preferably composed of one piece.` When each member is of compound construction it will have opposite upper and lower walls 14, 15, and said walls receive between them an extended end oit the corresponding tongue 12 or 13, as the case may be, and these eX- tended ends are placed between the said walls 1d, 15, the three elements being secured together, as by rivets lila, the ends of which are countersunk in the walls. ln practice, it is preferred to spot-weld the walls 1d, 15 to the extended end oit each tongue, so that an integral structure is provided.

Each member composed ot thewalls 14, 15 and the part therebetween is provided with a longitudinal bore or hole 16, if that be desired, for the sake oli' securing lightness. Each member 1() or 11' is provided along one edge with a deep longitudinal recessl?, the bottom oi which recess is vpreferably located at about the mid-width of each member. The recessed body portion o1c each member 10 and 11 is provided with an under-cut groove 18, which extends longitudinally thereof along one side ot the body portion, and this recess is continued in the tongue 12 or 13 ot the members; By under-cutting the body portion of each member l0 and 11, an overhang' lip i9 is provided, which extends longitudinally of the body portion and longitudinally ot the tongue.

'.lhe members ot the extension or adjustable furniture, being counterparts of each other, preferably, the tongue oi' one member will be received in the longitudinal recess of the other member in such way that the under-cut groove 18 ot each member will receive the overhang lip 19 ot the other member. rtherefore, the two members mutually engage each other, and each may slide upon the other tor longitudinal contraction or longitudinal extension of the furniture. rEhe engagement of each longitudinal lip 19 oit one member with the longitudinal undercut groove 18 of the other member will preclude transverse separation oi the two mem- Y bers, and the width of the furniture will always, in this preferred embodiment of the invent-ion, be maintained uniform through out the `furniti'ire. For the purpose ot preventing longitudinal separation of the two members` one member is provided with a longitudinal. groove 2G, in which engages a pin or tongue 21 on the other member, said adjustable furniture is preferably composed' of two members which are inseparable from each other, and which cannot be separated transversely from each other. In other words, each piece of furniture preferably constitutes al unit, the parts of which will always be assembled. ln cross section, the

let

furniture is preferably rectangular, and will at least have square edges which are parallel, so Vthat the furniture may be properly set upagainst the type and the chase. It will be observed that it is not necessaryto make use of friction for binding the parts of the furniture together, inasmuch as they are preferably always held together so that they can be handled as a unit.

The opposite faces of the body portions of the two members are preferably provided with transverse ribs 22, 23, which are spaced at suitable distances apart. These ribs, serve to reinforce the structure of each memberof the furniture transversely, that is,they give transverse strength where the pressure is applied in the chase. The ribs which rest upon Vthe imposing surface also serve to raise the furniture thereabove to reduce the friction ywith such surface in adjusting the furniture, and the furniture may be conveniently adjusted by the engagement of the fingers of the printer with the upper transverse ribs, or the shoulders 'formed thereby. The ribs or shoulders 22, 23 pro- Vvide means Vfor accomplishing the several endsreferred to, and provide a practical structure for otherwise light furniture.

Each member of the furniture is preferably made of pica measurement from edge to edge, and of pica measurement longitudinally.

It will be seen that in the specific form of the invention illustrated, the adjacent surfaces of the extension members lie in contact throughout when the members are collapsed. Consequently, except for such bores 16 in the members as tend to lighten them, the said members are practically solid transversely.V It will furthermore be seen that the groove or slot` 20 in one of the members provides at the extreme inner end of that member a stop-shoulder' for the tongue or pin 2l, so that both members can be extended for substantially their full length, but cannot be separated by their longitudinal extension. Also, the engaged extension members of the furniture arelongitudinally divided in counterpart halves at the plane of separation formed by the undercut recessin one member and the lip of the other member. More specifically, the undercut recesses and the lips of the two members engage each other for the purpose of preventing transverse separation of the members, substantially coincident with the longitudinal axis of the furniture.

It is obvious that the invention is susceptible of more or less modification, as

Vparts may be omitted, parts added, and

parts modified, without departing from the scope and spirit of the invention, as defined in the claims; as for instance, the upper and lower faces of the furniture may be plain throughout the length of the furniture, except that, for instance, countersunk depressions at suitable intervals may be formed in said faces, and such depressions will enable the several functions which are accomplished by the transverse ribs'to be gained in perhaps as desirable a manner.

lllihat I claim is: j
